Calculate Distance Between Two Points Using Python

Program Overview

This Python program calculates the distance between two points in a 2D plane.
It uses the Euclidean distance formula:
distance = √((x₂ - x₁)² + (y₂ - y₁)²)

Python Code:

import math

# Read coordinates from user
x1 = float(input("Enter x₁: "))
y1 = float(input("Enter y₁: "))
x2 = float(input("Enter x₂: "))
y2 = float(input("Enter y₂: "))

# Calculate Euclidean distance
distance = math.sqrt((x2 - x1)**2 + (y2 - y1)**2)

# Display result
print("\n--- Result ---")
print(f"Distance between the two points: {distance:.4f}")

Sample Output:

Enter x₁: 2  
Enter y₁: 3  
Enter x₂: 7  
Enter y₂: 6  

--- Result ---  
Distance between the two points: 5.8300

Step-by-Step Explanation:

- The user enters coordinates for two points
- The program applies the Euclidean formula using math.sqrt()
- The result is printed with four decimal places
